IDirectDrawStreamSample::SetRect method (ddstream.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Note This interface is deprecated. New applications should not use it.

Changes the clipping rectangle for a sample.

Syntax

HRESULT SetRect(
  [in] const RECT *pRect
);

Parameters

[in] pRect

Pointer to a RECT structure that specifies the stream's new clipping rectangle.

Return value

Returns one of the following values.

Return code	Description
DDERR_INVALIDPIXELFORMAT	The stream isn't compatible with the pixel format.
DDERR_INVALIDRECT	The specified rectangle is invalid.
DDERR_INVALIDSURFACETYPE	The stream isn't compatible with the surface.
E_POINTER	One of the pointers is invalid.
MS_E_SAMPLEALLOC	The stream format doesn't match the surface and samples are currently allocated to the stream.
S_OK	Success.

Remarks

Both parameters are optional; set either to NULL to avoid changing that value. If the surface format doesn't match the stream format, this method fails.

If the new rectangle's size isn't the same as the current rectangle, a call to this method will fail.
